||Allows Heli Pilot to detect and shoot Camo Bloons.
||~ BTD6 description
IFR is the second upgrade of Path 2 for the Heli Pilot in BTD6. It allows the Heli Pilot to target and pop Camo Bloons.
It costs $510 on Easy, $600 on Medium, $650 on Hard, and $700 on Impoppable.
- This upgrade is very useful for Camo Rounds, such as Round 42. It is especially good for Round 78 if upgraded to Apache Dartship.
- While this upgrade only adds Camo detection, it inherits the buffs of Bigger Jets, so this can be a good crosspath if Heli speed is necessary.
